- ... Bovine herpesvirus-1 (BHV-1) causes infectious bovine rhinotracheitis (IBR), and infectious pustular vulvovaginitis (IPV) in cows and infectious pustular balanopostitis (IPB) in bulls worldwide. Infection of seronegative cattle with BHV-1 leads to abortion, retention of fetal membranes, increased service per conception, metritis and oophoritis. As part of an ongoing study on infectious causes of r ...

In this cross-sectional study, we used data collected from 304 cattle herds in New Zealand during 2015/ ...
